ABSTRACT:
A marking kit whose constituents are capable of forming a marking material includes a polymeric matrix-forming material and coated glass beads for incorporation into the matrix. Surface coated glass beads suitable for incorporation into the matrix are also disclosed, as is a process for the surface coating of the glass beads, a reflective surface marking comprising a synthetic polymeric matrix incorporating the coated glass beads; and a process for the reflective marking of a surface. Glass beads are surface coated with a material effective to provide the coated glass beads with a surface tension greater than that of the matrix-forming material and ranging from 30 to 70 mN/m. In the surface treatment, the beads may be brought into contact with at least one organic or organo-metallic compound selected from the group consisting of chloro-, boromo-, iodo-, amino-, chloroamino-, mercapto-, and epoxy-compounds to form a coating on their surface of a type which makes them hydrophobic and gives the beads a surface tension within the most preferred range of 30 to 51 mN/m. The reflective surface marking may be formed by applying a suitable thickness of polymeric matrix-forming material on a surface, such as pavement, and sprinkling and coated glass beads on the surface of that matrix-forming material before it hardens.
